Because sound waves are displacements of molecules of the medium they travel through, reducing the amplitude would mean decreasing the displacement the molecules experience as the wave passes through.
Even though sound waves are longitudinal (meaning the displacement is in the direction the wave travels in) and waves in water are transversal (the displacement is perpendicular to the wave's direction), an example can be found in water waves; reducing the amplitude in water waves would reduce the size/height of the waves.
In the case of audible sound waves reducing the amplitude will decrease the volume of the sound.

Increasing the amplitude of a sound wave?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing. The loudness of 1 sone equals the loudness level of 40 phons (at 1 kHz).
Can sound waves break ice?
Yes, if the sound waves were generated with a frequency that matched the natural frequency of the ice, resonance would occur. If the amplitude i.e. the sound was loud enough, and the frequencies were matched, the ice could vibrate with enough force causing it to shatter.
What units are used to measure sound energy?
The total energy in a specific sound can be measured but that is not the normal way of reporting sound energy.Sound energy is typically characterized as power (energy per unit time) per unit area. The standard units (SI) of sound intensity are W/m2 (watts per square meter).When sound is measured by a sound meter, the result is often reported as a "Sound intensity level" that is expressed in decibels and compared to a defined standard of one picowatt per square meter.There are other measures, such as "sones" which are meant to characterize perceived loudness, but that it not a standard (SI) measure.In standard units then, total energy would be joules, power would be watts, intensity would be watts per square meter.
What is the vertical distance between the highest and lowest points of a wave?
The amplitude of a wave measures the height of a wave, as commonly depicted on a 2-D graph. However, amplitude tends to measure purely the absolute value of the distance from 0 or the baseline. So a wave with a height of 2 would not be said to have an amplitude of 4 due to the height above and below 0, but rather just an amplitude of 2. Hope this helps.
What would happen if the guard cells are closer together?
The stomata would be narrower, thus osmosis would occur less, thus photosynthesis would be less. The stomatal pore will become narrower. Gaseous exchange to and fro stomata will be reduced. This will affect the rate of photosynthesis in green plants.
When a sound wave is diffracted is the amplitude always reduced?
No. A wave travelling in the opposite direction would have its amplitude increased.
What would happen to a sound wave if the energy increased?
It becomes louder. The amplitude of the sound wave increases
Does amplitude mean louder?
Amplitude refers to the intensity or volume of a sound wave. A higher amplitude generally corresponds to a louder sound, while a lower amplitude corresponds to a quieter sound.
If the amplitude of a sound wave is increased by a factor of four how does the energy carried by the sound wave in a time interval change?
If the amplitude of a sound wave is increased by a factor of four, the energy carried by the sound wave in a time interval will increase by a factor of sixteen. This is because energy is proportional to the square of the amplitude of the wave.
Does intensity increase with the amplitude of a sound wave?
Yes, generally, intensity does increase with the amplitude of a sound wave. The intensity of a sound wave is directly proportional to the square of its amplitude. This means that if the amplitude doubles, the intensity will increase by a factor of four.
How are the sound wave when whispering?
When whispering, the sound waves produced are of lower intensity and frequency compared to normal speech. The amplitude of the sound wave is reduced, resulting in a softer and less audible sound. This is why whispering is often used in situations where you want to keep a conversation private or not disturb others nearby.
What does wave amplitude measure?
Wave amplitude is the strong or weak of the wave, like in sound, it would be the volume.
How would you describe amplitude to someone learning about sound?
Imagine a vibrating pendulum moving back and forth. Amplitude in sound is the size of the air particles vibration during the sound.
How is volume changed in sound?
The volume of sound is changed by adjusting the amplitude of the sound wave. Increasing the amplitude makes the sound louder, while decreasing the amplitude makes it quieter. This is typically achieved using a volume control mechanism in electronic devices.
What are the characteristics of a sound wave that you would interpret as loudness?
The characteristics of a sound wave that determine loudness are amplitude (height of the wave, which correlates with volume), frequency (pitch or tone of the sound), and duration (length of time the sound persists). A higher amplitude wave indicates a louder sound.
Can you change the amplitude in maracas?
No, you cannot directly change the amplitude in maracas. The amplitude of a sound wave produced by maracas is determined by the force with which they are shaken. The harder you shake the maracas, the greater the displacement of the seeds inside, resulting in a higher amplitude sound wave.
What is The interaction between waves that meet is?
Interference. This can result in either constructive interference, resulting in increased amplitude, or destructive interference, whereby there would a reduced amplitude.
